Exercise 5 : Question 6 (60)

Explain the difference:

Conventional Sources of Energy	Non-conventional Sources of Energy
1. The conventional sources of energy are generally non-renewable sources of energy.	1. Non-conventional sources of energy are generally renewable.
2. They are being used since a long time.	2. They are yet in the process of development.
3. Conventional sources of energy include coal, petroleum, natural gas and hydropower.	3. Non-conventional sources of energy include solar, wind, tidal, biogas and biomass, geothermal energy.
4. They cause pollution when used, as they emit smoke and ash.	4. They are generally pollution free.
5. Power plants running on these are very expensive to be maintained, stored and transmitted as they are carried over long distance through transmission grid and lines.	5. Power plants running on these are less expensive due to local use and easy maintenance.
Thermal Electricity Generation	Solar Thermal Electricity Generation
1. Thermal electricity is generated by using fossil fuels like coal, natural gas and nuclear fuels like uranium and plutonium.	1. Solar thermal electricity is generated from solar radiation.
2. Thermal electricity causes pollution and is not eco-friendly.	2. Solar thermal electricity generation does not cause pollution and is eco-friendly.
3. Their reserves are limited and will soon get depleted.	3. These energy sources are never ending and perpetual.
4. The electricity generated has to be carried to far off places.	4. Electricity can be generated locally.
5. It causes health hazards and acid rain.	5. It does not cause any health hazards.
6. Energy generated is not green energy.	6. Energy generated is called green energy.
